DDRC-24, a USB DAC+DSP Digital Room Correction processor powered by Dirac Live in a tiny form factor

miniDSP introduces the DDRC-24, the world’s smallest Dirac Live® hardware processor. Dirac Live®, the world’s premier room correction solution, is now available in an unbelievably compact hardware unit. Powered by a 400 MHz Analog Devices SHARC processor, the DDRC-24 retains the 4-channel output of its sister unit, the miniDSP 2x4 Hd, in order to allow applications like subwoofer integration or even 2-way loudspeakers together with Dirac Live® room correction in a single tiny hardware platform. The matrix mixer and crossover functionality is accessed and programmed with miniDSP’s easy-to-use interface software. An all in one unit with USB DAC + Dirac Live Room Correction + Speaker processing.

I/O capabilities get an upgrade too, with the addition of USB audio streaming up to 192 kHz and a TOSLINK digital input. The miniDSP DDRC-24 will find application in full-sized hifi and home theater systems, on desktops, in cars, in recording studios anywhere a compact, powerful room correction processor is needed.

Optional Accessories

  • WI-DG for Wifi/Alexa voice control of your unit. Note only the plugin is controllable via Wifi. Dirac Live still requires a USB connection unfortunately.
  • Audio RCA cables

NOTE: The UMIK-1/2 are measurement microphones approved by Dirac Research. Knowing the major effect a wrong calibration/measurement would have on the final results of Dirac Live tuning, we strongly recommend that you select a UMIK-1/2 microphone together with your platform for a plug&play experience leading to best results. Any issues related to 3rd party microphones such as ASIO/USB audio driver incompatibility/Latency problems or incorrect calibration process will not be under our support structure by our support team.
